It would be fascinating to learn how this works out. What an interesting position for Upwork to be in. A relatively iron-clad rule vs. religious tolerance. I am not smart enough to figure this stuff out. I'd love to know how it was resolved.

Upwork simply allows freelancers to verify their identity by making special arrangements (such as allowing Muslim women who wear a veil to do video verification with a female agent), and then the freelancers are allowed to use a photo in which they wear their religious garb.
